摘要

Three approaches were used in a site-specific sediment toxicity evaluation for hexachlorobutadiene(HCBD), a chemical not previously tested for toxicity in sediment. The results of a sediment dilution study, spiked sediment toxicity tests, and a probabilistic model based on equilibrium partitioning theory were used to estimate ecological effects thresholds for HCBD in sediments of a Gulf Coast estuary. Twenty-nine sediment samples, including 11 undiluted samples and six dilution series, were tested for toxicity under estuarine conditions(10/100 salinity)using Hyalella azteca and Leptocheirus plumulosus.
